Feature Description
Remote On/Off
The Austin Lynx
TM power modules feature an an On/Off
pin for remote On/Off operation. The On/Off pin is pulled
high with an external pull-up resistor (typical Rpull-up =
68k, ± 5%) as shown in Fig. 28. When transistor Q1 is
in the Off state, logic High is applied to the On/Off pin
and the power module is Off. The minimum On/off
voltage for logic High on the On/Off pin is 1.5Vdc. To
turn the module ON, logic Low is applied to the On/Off
pin by turning ON Q1. When not using the negative
logic On/Off, leave the pin unconnected or tie to GND.

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current limiting
continuously. At the point of current-limit inception, the
unit enters hiccup mode. The unit operates normally
once the output current is brought back into its specified
range. The typical average output current during hiccup
is 3A.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point Tref, exceeds
125
oC (typical), but the thermal shutdown is not
intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restarts after it cools down.
Output Voltage Programming
The output voltage of the Austin Lynx
TM SIP can be
programmed to any voltage from 0.75 Vdc to 3.3 Vdc by
connecting a single resistor (shown as Rtrim in Figure
31) between the TRIM and GND pins of the module.
Without an external resistor between the TRIM pin and
the ground, the output voltage of the module is 0.7525
Vdc. To calculate the value of the resistor Rtrim for a
particular output voltage Vo, use the following equation:

For example, to program the output voltage of the
Austin Lynx
TM module to 1.8 Vdc, Rtrim is calculated is

By using a 1% tolerance trim resistor, set point
tolerance of ±2% is achieved as specified in the
electrical specifications. The Lynx Programming Tool,
available at power.tycoelectronics.com under the
Design Tools section, helps determine the required
external trim resistor needed for a specific output
voltage
